To all 'uf/1.0m. t may concern Be it known that 1, AUGUSTUS F. HARTER, a citizen o1 the United States, residing at Chicago, county of Cook, State of illinois, have invented a certain new and useful Improvement in Combined Cooking and Heating Stoves, and declare the following to be a full, clear, and exact description of the saine, such as will enable others skilled in the art to which it pertains to malte and use the same, reference being had to the accompanying drawings, which form a part .of this specification. y

My invention has for its object to produce a simple and novel stove adapted for lboth cooking and heating purposes.

A further `object of my invention is to produce a simple and novel stove structure which may easily and conveniently be changed so as to adapt the stove to use either wood or coal as a fuel.

A further object of my invention is to produce a simple and novel stove having a large water-heating capacity so as to provide hot water for yvarious purposes including the heating ofy rooms by means of hot Vater radiators.

A further object oi' my invention is to produce a simple and novel stove having a relatively'large heating coil, provision being made for permitting the insertion and removal of the coil bodily soas to permit it to be madek up and tested before being assembled in the stove. f

A. further obfect of my invention is to produce a novel arrangement for supporting a tire pot in a stove having heating coils along several of its walls.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but, for a tull understanding of my invention and of its various objectsand advantages, reference may be had to the following detailed description taken in connection with the accompanying drawings, wherein: y

Figure 1 is a front elevation of a stove arranged in accordance with `apreferred form of my invention adapted orburning wood; Fig. 2 is a front view of the stove with the stove^ front removed, the i stove being provided with a tire pot to adaptlit'lto the burning of coal; Fig. y3 is a transverse section on line 3--3 of Fig. 2; Fig. tis a 'front .elevation of the stove front which is used on the stove when the latter is equipped with the fire pot as illustrated in Fig. 2; Fig. 5 is a side view of the stove on a reduced scale showing the manner of connectving. they heat-ing coil therein to aradiatoror thehke at a remote point as, :tor example,

in a room other than that in which the stove is placed; F ig.. 6 is a transverse section through the' stove just above the supports for the fire pot, the heating coil and the lire pot being omitted; Fig. 7 is a section on an langed scale on line 9-9 ot Fig. 6; Fig. 10

8 is a section on an enlarged scale on line 8--8 oFig. 6; Fig. V9 is a section on an enlarged scale on line 9-9 of Fig. d; Fig. 10 is an inside elevation of a portion of the left hand side of the stove, showing the supports tor the re pot strips and one of the supports for the heating coil; Fig. 11 is a plan view on an enlargedl scale of the front end of one of the lire pot strips, illustrating the means for adapting it to various conditions encountered; Fig. 12 is a side .view of the Jfragment shown in Fig. 11; Fig. 13 is a hori- Zonta-l section through one of the.. front corners of the stove, illustrating a modiiied arrangement for fastening the front to the sides; Figsli and 15 are a plan and a side view of a clip for holding a copper heating coil in place; Fig. 16 is a detail o1 the reducer for the opening through which the pipe Vleading to the heating coil extends.

Referringto the drawings, 1 represents the back` and Q- and 3 the sides or ends kof a stove. p

' 4; yisthe bottom or base and 5 is the stationary `portion ot the top. Along the front edges of .the sides or 'ends and the top are outwardly facing seats 6, 7 and 8, respectively, against which the iront of the stove is adapted to tit, the front being thus detachable without removing or displacing the topY or'fthe sides. This has several advantages, one ofthem being that when the stove is to be used as a wood stove, it may be provided with a front such as indicated at 10 in Fig. 1. On the other hand, when it is desired` to change the stove into a coal stove the front 10 may easily be replaced by another front, 11, indicated in Fig. L1. nother advantage of the front which is removable without dismounting the top or the tion ofV a fire pot, heating coils or other parts. Along the bottom is a seat 9 in which jpassingdown through the top and the upper part of the stove front hold them to'- gether. I also employ the loose bolts Vor rivets 16 Vfor the purpose of holding in place a suitable reflector 17 which has a portion overlying` the flanges 13 and 14vso that the rivets may pass down through a part of the refiector before they enter the flange 14. Just below the rivet-receiving openings 18 in the flange 14 areV lugs 19 with which the lower ends of the rivets engage and by which they are steadied.

One of the purposes of my'invent-ion is to produce a stove which will heat Aa large amount of water, so as to supply not only a i hotwvater tank such as kit is customary to have in kitchens but also a radiator or radiators which may be located in a room other than that which contains the stove; so that VVthe stove may be used for heating a roo-1n,

.for cooking purposes, for maintaining a supply of hot water, and for heating another room or rooms. To this end I have provided a large heating coil 40 which is made up of pipe extending back and lforth across the back of the stove and from the front to the back on each side or end of the stove, the coil, if desired, extending substantially from the bottom to the top of the stove. By making thek fro-nt of the stove removable in the manner heretofore described, the heating coil may be completed as a Aseparate unit and tested before being placed into the stove. In the same way when it is desired to move the coil for any purpose, it is only necessary to remove the front of the stove, whereupon the coil may readily be slipped out. In the arrangement shown, the tw'o ends of the coil are near the right hand side of and at the back of the stove, connections being made by passing the ends of the coil' or suitable elbows or couplings through openings 41 in the back of the stove. Inthearrangement sho-wn, the coil is made up of ordinary iron y pipe with the necessary elbows and return bends, but it will of course be understood that the coil may be constructed of a single piece of pipe, of copper or any other material, bent into the desired shape. Where copper pipe is used, it will be smaller in diameter than the iron pipe and therefore I have provided the device shown in Fig. 16 for reducing the size of the openings 41; this device consisting simply of two halves of a ring 42 hinged 'together at one end as at 43 and overlapping at the other end as at 44, the opening within the ring being just large enough to receive the copper pipe. TheA device is secured in place byr screwing the hinge screw or boltinto the back of the stove so that the same part serves to Vhinge the two halves of the ring together and to fasten them to the stove.

In order to prevent the elements of the heating coil from sagging I have provided the back and the sides or ends of the stove with inwardly extending projections as indicated at45 and 46; these projections being long enough to extend into the spaces between the elements of theccil when the coil is placed in the stove, and being sospaced apart that the coil will be efliciently supported from beneath at a. considerable number of distributed points.

As I have heretofore explained, the stove is adapted to burn either wood or coal as a fuel. In burning wood there are no other parts inside of the stove except the heating coil. Forburning coal it is necessary to have a fire pot and grate and an ash pit into which the ashes may drop.

One of the features of my invention has to do with a novel means for supporting a firepot construction, including the grate, in such a manner that it may readily be placed in position or removed without interference with the heating coil and without making it necessary to take the heating coil out. To this end I have arranged, about midway between the top and the bottom of the stove, supporting ledges and lugs, some of which are adapted to support the fire potdirectly and others of which are adapted to support detachable fire potstrips. The details of this construction are best shown in Figs. 6 to 12 inclusive, Figs. 2 and 3 showing the features in the assembled stove. Along the back of the stove is a narrow horizontal ledge 50 which is interrupted at a short distance from each end or side of the stove as indicated at 51 (see Fig. 9). Just below the point at which the ledge is interrupted are lugs 52 and, at each end of the central portion of the ledge Ais'an'inw'ardly projecting shoulder 53 arrested above the ledge. Along each side of the stove, at a slightly higher elevation than the ledge 50 is an inwardly-projecting, narrow ledge 54; and beneath each ledge 54 are several inwardly projecting lugs 55. Across the front of the stove is a narrow ledge 56 which is provided with open top pockets 57 and 58 near its ends and with upwardly inclined portions 59 and 60 beyond the pockets. At each side of the stove is a fire pot strip, as indicated at 61 and 62. The rear end of each strip is adapted to rest upon one of the end sections of the ledge 50, vhas a. part 63 resting upon the lug 52, and has a shoulder 64 bearing against the shoulder or projection 53. VThe outer side edges of the fire pot strips are adapted to underlie the side or endV ledges 54 and to rest upon the lugs or projections 55. At the front ends the fire pot strips rest within .the pockets 57 and-58 and, in some instances on the members59 and 60. 0n their' inner edges the fire pot strips have depressed seats and 66, respectively which with `the ledge 56v and the central portion of the ledge 50 form a continuous seat for receiving. the lire pot..

67 is a lire pot of Lany suitable construction having around the top thereof an outwardly projecting flange 68 which is adapted to rest upon the seat which I have just described. yThe lire pot stripsare wide enough to extend beyond the inside of the end elements of thecoils so that the coils are not in the way of the fire pot. It is not necessary to have a detachable strip at the back of the stove since the lire pot may be inserted from the front or diagonallv through the top in such a manner that a wide flange 69 on the rear side of the fire pot may be slipped in between two elements of the coil, It will berseen that when the tire pot is in position there is no possibility of displacement oi the strips, so that no fastening means are required for the strips, `the strips being simply laid loosely in the seats provided for them. The parts are soproportioned that the lire pot strips are higher at their outer edges than at their inner edges so that coal or ashes will not collect thereon but will fall by gravity back into the fire pot.

In the arrangement shown, the front end of one of the re pot strips encounters one of the return bends in the coil and therefore I have cut away this strip as indicated at 70 so as to leave an opening between the ledge portion 59 and the fire pot strip 62 large enough to receive the return bend in the coil. In case it is desired to dispense with the coil, this opening may be closed by a detachable piece 71 which is shaped to fit in a seat 72 at the front end ot' the strip 62 and is adapted to be secured by means of a bolt or screw 73 which passes down through an elongated slot 74 in the strip. When the member 71 is in place, the front end thereotl overlaps the inner end of the ledge member 59 and closes the opening between this member and the main portion of the strip. Where a copper heating coil is used, the opening at the front end of the strip through which it must pass is smaller than that required for an iron pipe and therefore I have provided the member 71 with a section 7 5 bounded by a groove 7G which weakens the metal so that the section '75 may readily be broken out. Consequently when a copper heating coil is used, the section 75 is broken out of the member 71 and the latter is secured upon the end of the lire pot strip and is adjusted within the limits alforded by the slot 74 so as to lit about the bend in the heating coil. In the arrangement shown it happens that the right hand fire pot strip is designed to accomrno date a return bend in the heating coil, but I donot desire to be limited to this arrange ment, since the same principle may be applied to the left hand strip ii'it is desired to have the heating coil so shaped as to bring a return bend opposite the front end of the left hand strip.

In Fig. 5 I have illustrated one of the novel uses of my heating coil. It will be seen that the stove is located on one side of a partition 77 and the heating coil, in addition to being connected to the usual hot water tank7 (not shown), has pipes 7 8 and 79 leading to a radiator 80 in a room on the opposite side of the partition; the large capacity of the heating coil permitting this eXtra duty to be placed upon it.

In Fig. 13 I have illustrated an arrangement for fastening the front to the sides, doing away with the lugs 12 or supplementing them. On the inner side of the front, near one or both side edges are detachably secured cleats. 951 which hook behind shoulders 96 on the interior of the sides. By unscrewing the bolts 97, with which the cleats are secured in place, the front is released from the sides.

`In Figs. 14 and 15 I have illustrated an adjustable clip for engaging with the bends of the heating coil when the latter is made of a piece oi copper pipe bent into shape. Each clip is made of a flat shank, 98, having a hook, 99, at one end, the hook being large enough to tit over the pipe. The shank is toothed on one side at 100 and has a slot 101 extending lengthwise thereof. At suitable points on the interior of the sides oit' the stove are ridges adapted to receive the teeth on the clips and cause the clips to be held firmly in any desired position. This is best shown in Fig. 10, 102 representing two ribs or beads having shoulders 103 and 104 at their ends. The shoulders 103 and 104e are just far enough apart to receive between them the shank of one of the pipe clips. Ba tween the ribs is a boltopening. 105. After the coil has been put in place, the clips are hooked over its turns and are bolted in place by suitable bolts passing through the openings 105 and the slots 101. the ribs 102 engaging with the teeth on the clips, and

the shoulders 103 and 104. supporting the clips in the vertical direction and assisting the teeth and ribs in holding the clips against rotation.

It will thus be seen that I have produced a novel stove construction which combines in a compact form a heating stove and a cooking stove together with a water heater of considerable capacity. It will also be seen that I have provided means which will permit the stove to be readily converted from one burning coal to one burning wood; it being only necessary, in order to change with particularity only a single structural' arrangement embodying the various fea-V "tures of my invention, I do not desire to be limited to the exact details illustrated and described; but intendto cover all forms and arrangements which fall within the terms employed kin the definitions of my invention constituting the appended claims..

I claim: y v

1. A stove containing` a Vheating coil lying close to the side or end walls of the stove, lugs on said wallsfbetween the top and bottom of the coil, fire pot strips inserted be-v tween elements of said coil and engaged with said lugs, and a fire pot supported on said strips.
